MACHINE FOR ROLLING PLOWSHARES.

Specification of Letters Patent.

Patented July 24, 1906.

Application iiled October 22,1903. Serial No. 178.099.

To all whom it may concern:

Be it known that I, OHAnLEs F. SPERY, a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in Machines forRolling Plowshares, of which the following is a speciiication.

This invention relates to metal-rolling machines, and is especiallydesigned for rolling plowshares to form the cutting edge thereof.

The object of the invention is to provide an improved construction andarrangement of bearings for lthe die and pressure-rollers,

.with means arranged between the said bearings for the die andpressure-rollers for equalizing the pressure on said bearings.

In the accompanying drawings, Figure 1 is a plan view. Fig. 2 is a frontelevation. Figs. 3 and 4 are end elevations.

The main supporting-frame comprises a base 1, having shelves 2 and 3,twoend uprights 4 and 5, connected by rods 6. Each end upright isprovided with a vertical opening 7. The mainroll 8 is supported inbearings 9 in the openings 7, and to one end is secured a toothed wheel10. A shaft 12 extends in the lengthwise direction of the machine andhas a toothed wheel 11, secured to one end, and a toothed wheel 13,loosely 'mounted on its other end. This shaft 12 is driven by the pinion14 on the shaft T1115,

. e shaft 15 is driven by a belt connecting the pulley 16 with the mainmotive power. A pinion 13 meshes With 'the toothed wheel 10, and as itis loosely mounted on the shaft 12 motion from the shaft will not betransmitted to the main roll 8 until a clutch mechanism, now to bedescribed, is thrown in. The pinion has a ratchet-toothed face' 17,forming one member of the clutch. On the shaft 12 is located the othermember 18 of the clutch and is constantly driven by a feather connectiontherewith. A band 19 is located around the member 18 of the clutch,havin its arms 20 pivoted to a sup ort 21, exten ing from the main frameandp held separated. Arms 22 have a connection with the band 19 andtheir free ends connected to a rin 23, located in an annular groove inthe mem er 18 of the clutch. A coiled spring 24 has one end connected tothe main frame and its other end the link 32.

ber 18 of the clutch in engagement with the toothed face 17 of the othermember. Be-

tween the arms 20 is located a block 26 in a manner to slide inconnection therewith and held from displacement by the dependingprojections 27, attached to it. A foot-lever 28 has a pivotal connectionwith the main frame intermediate its ends. Its inner end engages the arm29, connected to a shaft 30, and to this shaft is connected an arm 31,having a4 connection with the projection 27 by By means of thefoot-lever the block 26 can be moved in its connection with the arms 20.

From the outer face of the toothed wheel 10 extends a wedge-shaped block33.

When the main roll 8 is at rest, the clutch members are disen aged andheld so by the Wedge-shaped bloc 33 engaging the block 26,*which in turnthrough the arms 20 hold the member 18 of the clutch separated from themember 17 and against the action of the spring 24. When it is desired toimpart motion tothe roller 8, a downward pressure of the foot-lever 28through the arms 29 and 31 and link 32, the lblock 26 will be movedtoward the rear of the machine free of the block 33, which will allowthe arms 20 to move on their pivotal connection, and the spring 24 willdraw the member 18 of the clutch into engagement with the member 17 ofthe clutc Vand as the member 18 is constantly rotating a rotary movementwill be imparted to the pinion 13' and through the toothed wheel 10 tothe main roller 8 until the main roller has made a complete revolution,when the wedge-shaped block 33 Will engage the block 26 and force themember 18 of the clutch from its engagement with the other member,thereby stopping the movement of the main roller 8.

Above the main roller 8 is located a smaller roller 34, held in boxes35, located in the openings 7 in the uprights of the main frame, andabove this roller is located a similar roller 36, held in boxes 37. Theroller 34 is held separated the pro er distance from the main roller 8by the a justing-screws 38, located between the boxes of the tworollersand by means of which the roper adjustment can be obtained. edges39 are placed between the boxes of the rollers 34 IOO and 36, by meansof which the pressure can ysecured a gage .41, also a dier42.
